I have nearly 7.5 bars and I go for a dyno ride, I had 97HP (72.3kW) wheel power. engine doesnt consumed oil, no black smoke at all, so? Is the compression tester faulty?

Don't think anyone has mentioned this yet, but worth remembering that the accuracy of compression testers, particularly cheap ones, is somewhat questionable, and as such a lowish reading across all four cylinders isn't always a cause for concern. What you're much more interested in is differences between cylinders - ideally you should have all four within about 5%, but 10% or so difference is acceptable.

Ok. Thanks for the answers guys. Does anybody has anything to say about my cam choice?
